"Walkers Approach of the description of the influence of loading cycle asymmetry in the high-cycle region consists in multiplying by a factor of Pm where P is one of used asymmetry parameters, defined by the quotien of maximum stress and stress amplitude. This approach can be relatively simply generalized also for low-cycle region as shown by the authors last year. Certain difficulty appears for high values parameter P when an unacceptable relation UTS < sigma c Pm (sigma c means fatigue limit) can be obbtained. It has a very unpleasant consequence in the High diagram construction: the curve does not cross the UTS value on mean stress axis as asked. The paper proposes a modification which is identical with walkers approach for lower values of asymmetry parameter P and, on the other hand, does not allow to overstep the UTS value for high values of parameter P. The advantage of this modification is best presented in the Haigh diagram." . . "P(GA106/03/1265)" . . . "Neuveden" . "0"^^ . "V\u011Bchet, Stanislav" .
